PROBLEM TO BE SOLVED: To provide a shake correcting device correcting shake without using a special sensor. SOLUTION: When a shake correction lens 10 is moved by camera shake, an electric current pass through the coil 330 of a driving force generating device 30. A driving current outputted by a driver 22 is measured by a driving current measuring device 5. An ideal driving current arithmetic part 6 calculates a virtual driving current in a state where acceleration caused by the camera shake is not imparted, based on a target position signal outputted by a position command value arithmetic part 7. The position command value arithmetic part 7 obtains a value in proportion to camera shake acceleration by comparing the driving current measured by the driving current measuring device 7 with the virtual driving current calculated by the ideal driving current arithmetic part 6. The position command value arithmetic part 7 calculates the driving quantity (target position signal) of the shake correction lens 10 required to cancel out the shake on a film surface F by calculating the shake angle of a camera from the camera shake acceleration. |
